Regulations require certified professionals for removals and disposal in compliance with local and federal guidelines, ensuring safety and legality.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

In the 1980s, the use of asbestos in house siding materials underwent a significant decline, ultimately being phased out by the mid-1980s to early 1990s. This change was largely due to a growing awareness of the severe health risks associated with asbestos exposure, particularly its link to lung diseases and cancers. With increased public concern and regulatory agency involvement, building codes and regulations were updated to restrict the use of asbestos in construction materials. 

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

When asbestos fibers become airborne, they enter a person's respiratory system. These fibers scar and damage the lungs and often lead to serious cancers like mesothelioma. Like many dangers in the house, asbestos isn’t easy to see when it could be causing serious damage. The amount of time exposed, combined with the person’s tolerance for asbestos inhalation and the amount inhaled, will all contribute to health problems.
